DESCRIPTION OF THE EMBODIMENTS

The technical solutions of the embodiments of the present applicationare clearly and completely described below with reference to theaccompanying drawings in the embodiments of the present application, itis apparent that the described embodiments are only a part ofembodiments of the present application, instead of all the embodiments.All other embodiments obtained by those of ordinary skill in the artbased on the embodiments of the present application without creativeefforts shall fall within the protection scope of the presentapplication.

A core of the present application is to provide an assembly chair, whichis high in assembly efficiency and does not use an assembly tool.

Referring to FIG. 1 to FIG. 3, FIG. 1 is a breakdown structuralschematic diagram of an assembly chair in a specific embodiment of thepresent application, FIG. 2 is a structural schematic diagram when theassembly chair in FIG. 1 is assembled, FIG. 3 is a partial enlarged viewof an internal clamping slab in FIG. 1, FIG. 4 is a partial enlargedview of an external clamping slab in FIG. 1, and FIG. 5 is a partialenlarged view of a clamping shaft and a clamping sleeve in an assemblychair in another specific embodiment of the present application.

In a specific embodiment, the assembly chair provided by the presentapplication includes a seat frame 2, a back frame 3 and two armrests 1.It is to be noted that the above three components are not limited to aspecific form or structure, may be a frame of the chair only, and mayalso be a component of a finished chair including various outerpackages. These components are not limited in manufacturing material,and may form a sofa, a bamboo chair or a wooden chair after assembly.

The seat frame 2 and the back frame 3 are rotatably connected to eachother, that is, both may be folded or unfolded. The rotatable connectionbetween the seat frame 2 and the back frame 3 may be implemented via arotatably-connected component. It is common that a plurality of hingesmay be provided at a junction between the seat frame 2 and the backframe 3. However, the installation of the hinge is not simple enough.

Therefore, in a specific embodiment, a first rotary connection component2 a and a second rotary connection component 3 a that are provided witha through hole thereon respectively may be disposed at the junctionbetween the seat frame 2 and the back frame 3. During assembly, thefirst rotary connection component 2 a and the second rotary connectioncomponent 3 a may be connected via a bolt, to implement the rotatableconnection between the seat frame 2 and the back frame 3.

The first rotary connection component 2 a and the second rotaryconnection component 3 a are often fixedly disposed on the seat frame 2and the back frame 3. Due to a small size, both the first rotaryconnection component 2 a and the second rotary connection component 3 amay be integrally produced with the seat frame 2 or the back frame 3.The first rotary connection component 2 a and the second rotaryconnection component 3 a may be provided only as one pair at a middleposition of the junction between the seat frame 2 and the back frame 3,and may also be provided as two pairs on two ends of the junctionbetween the seat frame 2 and the back frame 3. Certainly, multiple firstrotary connection components 2 a and the second rotary connectioncomponents 3 a may also be provided.

Each of The two armrests 1 is fixedly connected to the back frame 3 viaa hand bolt 4. Specifically, a through hole may be provided on the twoarmrests 1, a threaded hole is provided on the back frame 3, and thehand bolt 4 is screwed to the threaded hole via the through hole,thereby fixing the two armrests 1 with the back frame 3. When thearmrest 1 and the back frame 3 are unsuitable for providing the throughhole or the threaded hole due to a material or a shape, other smallcomponents may be used. For example, a small component having a throughhole and a threaded hole is fixedly disposed on the armrest 1 and theback frame 3.

Herein, multiple hand bolts may be provided as required, and may besymmetrically disposed on the two armrests 1, thereby being practicaland beautiful. Additionally, the hand bolt may be a hand bolt having ahead machined by injection molding. Such a bolt is more favorable to amanual operation and does not need other tools.

The seat frame 2 is clamped between the two armrests 1, which is morefavorable to manual assembly. During specific assembly, it may beappropriate to first rotatably connect the seat frame 2 to the backframe 3 and then fixedly connect the two armrests 1 to the back frame 3.Certainly, it may also be appropriate to first fixedly connect the twoarmrests 1 to the back frame 3, and then rotatably connect the seatframe 2 to the back frame 3. Upon the completion of the above assemblysteps, the seat frame 2 is clamped with the two armrests 1 at last.Specifically, referring to FIG. 2, just a front end of the seat frame 2is clamped with the two armrests 1 from top to bottom.

The clamping connection between the seat frame 2 and the two armrests 1may be completed in multiple clamping manners. Generally, clampingpieces capable of matching to each other may be simultaneously providedon the seat frame 2 and the armrests 1.

In a specific embodiment, an external clamping slab 1 a and an internalclamping slab 4 a that may match to each other may be simultaneouslyprovided on the seat frame 2 and the armrests 1. The external clampingslab 1 a is fixedly disposed on each of the two armrests 1. The internalclamping slabs 4 a are respectively and fixedly disposed at two sides ofthe seat frame 2. Specifically, each of the internal clamping slabs 4 ais disposed at a junction between the seat frame 2 and each of thearmrests 1. The fixation manner may be welding or bolt connection, andthe latter is more convenient for maintenance and replacement. Aplurality of grooves 1 b for limiting the internal clamping slab 4 a maybe provided on the external clamping slab 1 a. Correspondingly,corresponding projections 2 b may also be provided on the internalclamping slab 4 a. During assembly, the internal clamping slab 4 a issleeved to the external clamping slab 1 a from top to bottom, and theprojections 2 b are respectively sunken into the grooves 1 b, therebycompleting the assembly.

In another specific embodiment, the clamping piece includes a clampingshaft 22 b and a clamping sleeve 11 a matching to each other. Duringassembly, the clamping shaft 22 b is sleeved to the clamping sleeve 11 afrom top to bottom.

The embodiments in the specification are described progressively. Eachembodiment attaches importance to describing a difference with otherembodiments. A same or similar portion of each embodiment may bereferred to each other.

The assembly chair and sofa provided by the present application aredescribed above in detail. In the specification, a specific example isused to describe a principle and an implementation manner of the presentapplication. The description on the above embodiments is merely helpfulto understand a method and a core concept of the present application.
